Overcurrent circuit breaker, 3P+N, C characteristic, 16A, 6kA, AC | S203-C16NA 2CDS253103R0164

Reliable protection of electrical installations – 3P+N circuit breaker

This three-pole circuit breaker with a neutral pole, C characteristic and a rated current of 16A, is a key element of every safe electrical installation. It provides effective protection against overloads and short circuits, minimizing the risk of damage and fires. The rated short-circuit breaking capacity of 6kA (AC) guarantees its reliable operation even in difficult conditions.

This circuit breaker is used in both home and commercial installations where high reliability and safety are required. Its compact dimensions (width 4 modules, depth 69mm) make it easy to install in distribution boards. Designed to operate in a temperature range from -25°C to 55°C, it will perform well in various environments.

Solid construction and wide possibilities

The circuit breaker is made of high-quality materials, which ensures its durability and resistance to mechanical damage. The possibility of connecting solid conductors with a cross-section from 0.75 mm² to 35 mm² and stranded conductors from 0.75 mm² to 25 mm² provides great flexibility during installation. Energy limitation class 3 and surge category III confirm its ability to protect against the effects of disturbances in the electrical network.

• C characteristic: provides delayed tripping during short-term overloads, which is particularly important for devices with motors or other elements generating high starting current – avoiding unnecessary tripping of the circuit when starting devices.
• Rated short-circuit breaking capacity: 6kA at 400V AC and as much as 20kA at 230V DC guarantees effective disconnection of the circuit in the event of a short circuit, protecting both the installation and people.
• Versatility: the possibility of mounting additional equipment allows the circuit breaker to be adapted to the specific needs of a given installation.
• Safety: meets strict safety standards (rated insulation voltage Ui: 440V, rated impulse withstand voltage Uimp: 4kV), providing protection against electric shock and other hazards.
• Durability: protection degree IP20 protects against finger contact and the ingress of solid objects larger than 12.5 mm – a solid construction ensures long-term use without failure.
